So, should you buy?
At $39.99, the current price reflects a 40% discount against the 365-day typical price of $66.39, and sits even below the realistically achievable low of $44.99.
That said, the absolute year-low of $39.83 held for only 0.1 day, so it's not a reliable target. The $44.99 level, by contrast, was reached 7 times and held for 71 days total, making it a far more realistic benchmark. The price is also quite volatile, shifting nearly every day, with a 25.2% upward trend over the past 90 days.
A price drop has been underway for 1 day, with roughly 12 days likely remaining based on past cycles (13 drops below the typical price this year, median duration 13 days, recurring about every 23 days). For sales events, Black Friday (36.6%) and Cyber Monday (35.8%) have historically delivered the best discounts. The current price already sits in favorable territory, acting now rather than waiting for a deeper dip seems reasonable.
The verdict
Buy now.
Worth it
